SOD C/C++ API Reference - Image Processing


sod_img sod_random_augment_image(sod_img input, float angle, float aspect, int low, int high, int size);


Perform small perturbations in scale and position to an input image. For standard image cropping, rotation & scaling you should rely respectively on sod_crop_image(), sod_rotate_image() and sod_resize_image().


sod_img    input

The input image to be processed. The image can be loaded from disk using sod_img_load_from_file(), from memory (i.e. network socket) via sod_img_load_from_mem() or dynamically created via sod_make_image().

float    angle

The rotation angle, in degrees. The rotation angle is interpreted as the number of degrees to rotate the image clockwise.

float    aspect

Aspect ratio.

int    low

Minimum scale range.

int    high

Maximum scale range.

int    size

Width & Height of the crop.

Return Value

Augmented image is returned in an instance of the sod_img object. if something goes wrong during processing, then an empty image is returned via sod_make_empty_image(). Once done, you must release the memory allocated to this object via sod_free_image() to avoid memory leaks.
